Product Description

The ECG012 is a high dynamic range driver amplifier in

a low-cost surface mount package. The InGaP/GaAs

HBT is able to achieve high performance across a broad

range with +36 dBm OIP3 and +20 dBm of compressed

1dB power. It is housed in a lead-free/green/RoHS-

compliant SOT-89 SMT package. All devices are 100%

RF and DC tested.

The ECG012 is targeted for use as a driver amplifier in

wireless infrastructure where high linearity and medium

power is required. An internal active bias allows the

ECG012 to maintain high linearity over temperature and

operate directly off a single +3 V supply.

This

combination makes the device an excellent candidate for

transceiver line cards in current and next generation

multi-carrier 3G base stations.
